FRICTION-CLUTCH.

To all whom it may concern:

Be it known that I, THOMAS W. MORGAN, a citizen of the United States ofAmerica, and a resident of Waterloo, Blackhawk county, Iowa, haveinvented certain new and useful Im )rovements in Friction Clutches, ofwhich the following is a specification.

My invention relates to friction clutches, and the object of myimprovements is to provide a simple and easily operated frictionclutchadapted to be quickly manipulated by hand to be engaged or separated asdesired. This object I have achieved by the mechanism which ishereinafter described and claimed, and which is'illustrated in the accompanying drawing, in which the figure is a central vertical axialsection of my said friction-wheel-conncction.

Similar letters refer to similar parts throughout the several views.

The end of the shaft a projects'a certain distancewithout the bearing 5.The projecting end of said shaft has a small excavated seat m for therece tion of the setscrew 0, the latter passing t irough abearingopening in the hub of the friction-disk k to secure the latter tosaid shaft. The frictiondisk It has a projecting hollow cylindricalextension or barrel n, and the head of the screw i is adapted to fitwithin the hollow of said barrel and be secured thereto by means of akey f inserted through registering channels in both said barrel and saidhead. The friction-wheel c has its hub fitted to rotate upon theexterior of the barrel n, and slidable thereupon to a certain extent.The friction-wheel c has a friction-ring Z adapted to contact with thefriction-disk f when the two are brought into close engagement. Athumb-piece 7L Works upon the screw 1', a washer being interposedbetween said thumb-piece and the ends of the barrel n and the hub of thefriction-wheel 6.

By turning the thumb-piece h a few times in one direction thefriction-wheel e is pushed toward the frame I) sufficiently to cause itsfriction-ring Z to closely engage with the friction-disk 7c. Motion thenim arted to said friction-wheel, causes the sha t a, to rotate,

Serial No. 373,187.

while the turning of the thumb-piece h in the opposite direction causesthe friction-wheel e to become disengaged from the friction-disk la, andto'rotate idly.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

1. A friction-clutch, consisting, in combination, of a driven shaft, afriction disk having a socketed hub detachably secured to the end ofsaid shaft, the socketed hub being extended outwardly from the outerface of said disk, a band -wheel having a socketed hub rotatably andslidably mounted on the outer extension of the socketed hub of saidfriction-disk and having a friction-surface adapted to be contacted withthe friction surface of said friction-disk, an axial screw having itshead detachably secured within the socket of said friction-disk andprojecting outwardly therefrom, and a thumb-nut mounted to work on saidscrew and detachably engage the outer surface of said bandwheel.

2. A frictionclutch, consisting, in combination, of a driven shaft, afriction-disk having a socketed hub detachably secured to the end ofsaid shaft, the socketed hub being extended outwardly from the outerface of said disk, a band-wheel having a socketed hub rotatably andslidably mounted on the outer extension of the socketed hub of saidfrictiondisk and having a friction-surface adapted to be contacted withthe friction-surface of said friction-disk, an axial screw having itshead detachably secured within the socket of said friction-disk andprojecting outwardly therefrom, a washer on said screw next to the outersurface of said band wheel, and a thumb-nut mounted to work on saidscrew and enga e said washer to cause the latter to frictionalfy engagethe outer surface of said band-wheel.
